Planning a call between London and Mumbai
Best window: 9 am to 1 pm in London (1:30 PM to 5:30 PM in Mumbai). In that stretch both cities sit inside core 9-to-5 hours, so neither side takes the call early or late.
Daylight saving
London is on UTC+1 (BST). Clocks go back one hour on Sunday, October 25, 2026, moving it to UTC+0. Between that date and the other city’s own change, the gap between them is an hour different from usual.
Mumbai does not change its clocks. It stays on UTC+5:30 (IST) all year, so the gap to the other city only moves when the other city shifts.
